Insert silence without overwriting audio

Hello all, I found out how to insert silence in my track but what it does is it overwrites the audio. So let us say I would like to add 5 seconds of audio between second 10 and second 11, so that all of the audio after second 11 moves 5 seconds backwards and second 11 becomes second 16?
Thank you!

Click on the track at the point where you wish to insert the silence. Do not click and drag (unless you want to overwrite part of the track), just “left click”.
Then open the “Silence” effect from the Generate menu.
Set the amount of silence that you wish to insert, and click the “OK” button.

Thank you so much, that was exactly what I was trying to do!
